Expert Answer:

Acids react with a base to form salt and water.


Acid                 +      Base    →         Salt         +           Water


In this reaction, an acid and a base neutralise each other’s effect. So, the reaction between an acid and a base to form salt and water is called neutralisation reaction.

For example:

  1. Hydrochloric acid reacts with sodium hydroxide to form sodium chloride and water. Sodium hydroxide and hydrochloric acid neutralise each other to form sodium chloride, a neutral salt.


HCl              +      NaOH    →         NaCl        +           H2O



  1. Sodium hydroxide also reacts with nitric acid to form sodium nitrate and water.


HNO3           +      NaOH    →         NaNO3       +           H2O
